Embodiment Construction

[0026] figure 1 For this application, a flow chart of an emergency treatment method for a tension leveler after the network is disconnected, such as figure 1 As shown, the emergency treatment method includes, step S10, detecting in real time whether the communication connection between the casting control master station and the tension leveler is faulty through the casting control slave station. Step S20, when it is detected that the communication connection between the casting control master station and the tension leveler fails, start the casting control slave station to control the operation of the tension leveler.

[0027] In the previous continuous casting process, if the communication network fails, the casting control master station will not be able to continue to send control commands to the tension leveler, so that the tension leveler cannot perform normal tension leveling work, resulting in a large amount of waste billets , or lead to problems such as casting device...

Abstract

The invention discloses an emergency processing method for network failure of a withdrawal and straightening unit and a system thereof. Whether a fault of communication connection between a casting control main station and the withdrawal and straightening unit occurs is detected in real time through a casting control slave station. When the fault of the communication connection between the castingcontrol main station and the withdrawal and the straightening unit is detected, the casting control slave station is started for performing operation control on the withdrawal and straightening unit.According to the emergency processing method for the network failure of the withdrawal and straightening unit and the system thereof, the communication connection condition between the casting control main station and the withdrawal and the straightening unit is monitored in real time; when the fault of the communication connection is detected, the casting control slave station is started for controlling operation of the withdrawal and straightening unit, thereby normally finishing a withdrawal and straightening process to a billet on the condition that a controlled state of the withdrawal and straightening unit by the casting control main station is lost, reducing forming amount of waste billets, or preventing fault problems such as casting speed reduction or casting stoppage of a casting device, reducing production cost, and furthermore improving cast steel quality, product qualified rate and production benefit.

Description

technical field [0001] The present application relates to the technical field of automatic control in the iron and steel industry, and in particular to an emergency treatment method and system for a tension leveler after the wire breaks. Background technique [0002] Continuous casting slab drawing and straightening refers to the process of pulling out the continuous casting slab from the crystallizer of the arc-shaped continuous casting machine at a certain casting speed and straightening it. It is one of the basic processes of modern continuous steel casting. The straightening machine is completed. [0003] The currently used continuous casting system includes a pouring device, a casting control master station, several casting control slave stations and several tension leveling devices. Among them, the tension leveling device includes a tension leveler, and a casting control slave station is connected to a tension leveler. The casting control master station communicates w...
